Application filed June 9, 1930. Serial No. 459,982.

The present invention comprehends the provision of'a soot extractor adapted to be associated with a chimney or the like, and

constructed to separate soot from the smoke or gases passing through the same.

One of the chief characteristics of the present invention resides in a construction of a device of the above-mentioned character, which not only separates the soot from the smoke and gases passing therethrough, but one which is also operable to return the soot to the chimney or stack when desired.

In carrying out the invention,'we employ a soot collecting housing supported above the chimney and open at both ends, and in which is arranged means for separating the soot from the smoke and gases passing therethrough, the housing having valve-controlled communication with the chimney, so that soot collected within the housing can be returned to the chimney asthe occasion may require.

An object of importance resides in the novelconstruction of means employed for loosening the soot from the walls of thehousing, when it is desired to return the soot and the like to the chimney.

More specifically stated, the invention comprehends means located within the housing for separating the soot'from the smoke or gases passing therethrough, including a normally seated valve which regulates or controls the return of the soot from the housing to the chimney,and which means is adapted to be vibrated within the housing with a view of loosening the soot from said means and also from the walls of the housing when it is desired to return the soot to the chimney. The nature and advantages of the invention will be better understood when the following detailed description is read in connection with the accompanying drawings, the invention residing in the construction, combination and arrangement of parts as claimed.

In the drawings forming part of this application like numerals of reference indicate similar parts in the several views and wherein:

" Figure 1 is a sectional view through the dedicates a soot collecting housing which is open at both ends, and adapted to be supported above achimney or smoke stack indicated at 11. It will be noted that the upper and lower portions of this housing 10 are of substantially frusto-conical formation as indi- 1 cated at 12 and 13 respectively. Depending from the lower end of the housing 10 is a hollow tubular member 14 which is partly received within the chimney or smoke stack 11, while carried by this member 141 at an appropriate point in its length, is an annular flange 15 which reposes upon the upper end ofthe smoke stack or chimney 11 as illustrated. The housing is supported upon the chimney or smoke stack by suitable rods 16 which are bolted or otherwise'suitably securcured to the housing at spaced points, the rods including extensions 17 which have their corresponding lower extremities oifset and embedded in the chimney 11. The rods 16 proJect an appreciable distance above the upper end of the housing 10 and support a conical-shaped cap 18.

Arranged within the housing 10 is a novel construction'of means for causing the smoke and gases passing therethrough to pursue its circuitous course, whereby the soot, cinders and the like are separated from the smoke and gases, and collected within the housing. This means includes a hollow tubular valve 19 which normally reposes upon the member 14, the latter constituting a seat for the valve as illustrated. Carried by this valve 19 at a point adjacent its upper end is a plurality of radially disposed webs 20 which connect and support a bottomless receptacle 21, constituting abaflie for the smoke and gases passing through the housing as will be readily understood. The receptacle parts, the smoke or gases emitted from the chimney or srnokestack 11 pass through the H r 19 into the ,bafiie-like receptacle 21, striking the conicah'top'ivall 22 thereof, and are thereby directed doWnwardly through the. open bottom of the re ceptacle 21, circulating around this receptacle in finding their way through the open upper end of the housing 10. However before the gases and smoke'escape fro'ni the housing 10, they strikethe, frustoconigal 114 2 f h 11 1 311hi i l gethsi with, the battle-like top [of hollow mam -M1 separatedifrpn i the. smoke and gases of course is collected by the i npi wh ehjalls to ing, ut some of which cling thereof including the, f rusto-conicaltop Wall 12.
